What blood oxygen levels are considered too high?
Oxygen saturation (SpO2) measures the oxygenated hemoglobin in the blood relative to the total amount of hemoglobin. Average SpO2 values usually range from 95% to 100% in healthy individuals at an altitude of 0 m.
It is essential to clarify that "high" blood oxygen levels are usually 100% or close to 100%, and values slightly above 100% may be measured due to pulse oximeter measurement error.
Hyperoxemia refers to an abnormally high level of oxygen in the arterial blood. This is the opposite of hypoxemia, which means a deficient oxygen level in the blood. Although oxygen is vital for properly functioning, too much can be harmful.
